Author Topic:   Ford 9 inch rear end question
posted March 23, 2003 08:29 PM
There is was on the third lap of packing the track and my left rear axle slides right out of the housing. I do not know much about the ford 9 inch as this is my first car. I bought it already set up and it had been raced before. My question is what needs to be done to ensure that not only this axle stays in place but also the drivers side? The drivers side has a small 1/4 inch wide by 1/4 inch thick collar spot welded to the axle inside the bearing. Both bearing are self contained, (one solid unit) no races. Would the collar be a good thing to do on the passenger side or is there a better way? Thanks for the help.

the collar you're speaking of should be a slight press fit. unfortunately, they don't always fit well and usually won't stand up to the side loads of oval track racing. it's good insurance to spot weld the collars.

you'll probably break the axle long before you need to replace the bearing. if you need to replace it after it's welded, grind the spot welds off and cut off the collar.

You do have the backing plate in between the bearing and flange?
The bearing is there to let it spin, the backing plate holds it in the housing.

Did the axle slide out of the bearing or did the bearing pull through the flat plate that holds the bearing in the housing?

Yep i had this happen to a GM rear with bolt in axles like the 9",luckily it didn't hurt anything and i got it welded at the track and it held for years afterwards,just don't get too crazy welding a good spot weld will do.
